I'm glad they made John an important character in season 3. He was kind of a side act in the first two seasons. I still remember seeing a post at a fan site that had the brief plot lines of season 3's episodes before the season started, and seeing things like, "John moving to New Jersey takes Tony by surprise", "John and Paulie strike up a friendship that Tony is unaware of", etc., and looking forward to it. Season 3 is when the true treachery begins in Tony's immediate crew, aside from Pussy in season 2, and Johnny Sack is in the mix of just about every incident.

"...the successful annihilation of organized crime's subculture in America would rock the 'legitimate' world's foundation, which would ultimately force fundamental social changes and redistributions of wealth and power in this country. Meyer Lansky's dream was to bond the two worlds together so that one could not survive without the other." - Dan E. Moldea
